ABSTRACT:
A composite overhead ground wire optical fiber cable of loose-tube type applying includes a first jelly paved on the circumference of the an optical fiber, for protecting the optical fiber against water; a plastics coating the circumference of the first jelly, for protecting the optical fiber against external shock; and a loose tube for inserting the optical fiber thereinto. An aluminum rod provides at least one groove for inserting the loose tube containing the optical fiber. A second jelly is paved between the loose tube and a surface of the groove, for fixing the loose tube therein and protecting it from water. A plurality of steel wires are externally provided around the circumference of the aluminum rod, for protecting the cable against tension stress and providing conductibility. The steel wires are aluminum coated, for protecting the steel wires against oxidation and corrosion.
